Cardiac transplantation in a 20

To describe cardiac transplantation in a young woman with juvenile onset diffuse scleroderma and cardiac involvement. Case report. A young White girl developed anti-topoisomerase-1 positive diffuse scleroderma aged 14？years with myositis. Pulmonary function tests were normal. Skin disease was treated with mycophenolate mofetil 1？g twice daily, methotrexate 7.5？mg weekly and periodic intravenous prostacyclin. When aged 17？years, she developed raised troponin T of 0.207？mcg/L (normal range <0.03) and NTproBNP (155？pmol/L); 6-min walking distance was 341？m, and she had episodes of presyncope with effort. The next year she developed symptomatic ventricular tachycardias and dual-chamber implantable cardioverter-defibrillator was inserted, with further episodes of ventricular tachycardia and one shock delivered. By age 19？years, 6-min walking distance was 125？m. Echocardiography showed ejection fraction of 15%–20% with dilated left ventricle and pericardial effusion. She was treated with intravenous Rituximab. She became breathless while dressing and managed only 118？m in 6？min. She experienced increasing orthopnoea and peripheral oedema and was found to be in a low cardiac output state, requiring treatment with intravenous milrinone to maintain renal function. She underwent orthotopic cardiac transplantation, making an excellent post-operative recovery, and was discharged 16？days later with tacrolimus, mycophenolate mofetil and prednisolone. After 1？year, she was in New York Heart Association functional class I and with normal cardiac function on echocardiography. This case illustrates the severe cardiac involvement that can occur in juvenile onset diffuse cutaneous systemic sclerosis, in which cardiac involvement is the leading cause of death
